Sprout is a plant experiment with a thick stem, several tentacle like vines, three leaves surrounding his head like a frill (one leaf is under his chin while the others are behind his head where his ears would be, if he had ears), a single antenna on his head, and a head shaped like a venus flytraps mouth with eyes. He's designed to grow into a forest of dark destruction, but is defeated as uprooted. His one true place is at the old water tower by the Planet Fair.


Sprout has made one appearance in the Stitch! anime and was mentioned in another. Though he did not officially appear in the second episode, his "offspring" did. It is revealed that Sprout can produce seed pods and launch them into space, where they cling to asteroids. One of these pods landed on the island and grew into a "Sproutling" (509-A) that carried out Sprout's original programming before being neutralized.


  • Sprout is an obvious parody of Audrey II from Little Shop of Horrors.
  • Sprout's pod color is blue.
  • In the battle between the Leroy army and the experiments at the end of Leroy & Stitch, Sprout did not spawn into an uncontrollable forest of destruction like he did in his episode.
  • In the English dub of Stitch!, Sprout has a son named Sproutling a.k.a. Experiment 509-A.
